Whether you’re getting a new air conditioner or looking to maximize your current one, getting it level is key.

Air conditioners are often installed on concrete pads. Over time, the pad can crack, shift or sink. This can cause malfunctions and even premature replacement. Let’s review some of the malfunctions that can happen and how to fix an air conditioner that isn’t level.

1. Your Air Conditioner’s Compressor Could Be Damaged

Your air conditioner’s compressor is a critical part. As its name suggests, it compresses liquid refrigerant that has turned into gas as it absorbs heat from your house. Once the compressor releases heat under pressure, the refrigerant turns into liquid again.

The compressor needs oil to run properly. If your air conditioner isn’t level, its oil could be distributed unequally.

This can create:

  • Compressor damage because of grinding parts.

  • A compressor that’s too hot.

  • Higher utility bills due to less efficient cooling.

The compressor is one of the most expensive components to replace on your air conditioner. If it breaks, you’re better off doing air conditioning installation due to this part’s cost.

2. The AC Unit Will Rust and Collect Mold

Water is a natural byproduct of the cooling process. Your air conditioner gets rid of moisture from the air as it cools your house. This moisture drains into a pan and then out through a line.

If your air conditioner isn’t level, water might end up accumulating in the pan instead of flowing away. This can lead to:

  • Water pooling around the air conditioner.

  • Rust and mold.

  • Damaged coils, which won’t be able to exhaust heat as well.

  • More expensive energy bills due to less efficient cooling.

3. Increased Wear and Tear

If your air conditioner isn’t level, it may vibrate more than normal. This can cause obnoxious sounds when on and even require air conditioning repair.

Excessive vibration could:

  • Place more strain on parts and wear them out faster.

  • Loosen refrigerant lines and create a costly refrigerant leak.

  • Make your air conditioner sink even more.

  • Eventually wear out your air conditioner much sooner.

Steps for Leveling Your Air Conditioner Pad

Leveling an air conditioner pad takes expertise. It’s usually not a job you’ll want to try on your own, since your air conditioner may need to be temporarily disconnected. This requires the assistance of a certified HVAC tech.
